Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dual-chip RFID on-skin tag for bilateral breath monitoring
No full textBreath monitoring is critical for multiple applications, ranging from monitoring patients in Intensive Care Units (ICUs) to the design of optimized physical training. Recently proposed Radiofrequency Identification (RFID) tags and systems for breath monitoring only return integrated information on breathing, whereas the air flow through each nostril can provide more useful information. In this paper, a dual-tag temperature-sensing RFID device is introduced for the simultaneous bilateral monitoring of the nostrils' breath. The device comprises two coupled tapered loops each closed to a transmission line probe excited by a smaller loop hosting the Integrated Circuit (IC). The resulting two-ports tag is such that each temperature-sensing IC is placed just below a nostril. Numerical and preliminary experimentations with epidermal prototypes suggest that the two sensors can be simultaneously read along the nose septum's direction up to a distance of 50 cm
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Evaluation of RESRAD-BUILD and MicroShield codes for the simulation of small accident scenarios in nuclear medicine therapy patients’ rooms
No full textComputational methods in nuclear medicine therapy can be very useful for estimating the external dose in non-routine situations when conventional dosimeters may be inadequate or unavailable. Monte Carlo techniques provide the most accurate approach when it comes to model complex scenarios, but they are time and machine resource consuming. In this work we explore the alternative of using two fast and interactive deterministic codes, RESRAD-BUILD and MicroShield, primarily designed for radiation protection purposes, to calculate the dose in small, simple accidental scenarios, and benchmarked them with two Monte Carlo simulation tools, MCNP6 and Geant4. The absorbed dose rate in air computed by RESRAD-BUILD and compared to MicroShield showed a mean ratio of 1.01 ± 0.04 for Lu-177 and 0.99 ± 0.04 in the case of a point source and within 25% for an area source. When compared to MCNP6 and Geant4, the results revealed an overall agreement among the codes, showing a deviation below 30% in most cases, with a few exceptions that are discussed. We also propose a preliminary approach for easy modeling of patient's organs to calculate the external dose from routine therapies with deterministic methods. The suitability and limitation of these models are presented and discussed for some common applications
